Please be aware that whether the case spigot deck and cylinder head sealing surface has been machined will affect the tensioner piston height. On mag case engines that have been rebuilt several times and those surfaces machined you will often be at the end of the tensioner range even with new chains. I have never found a satisfactory method to check chains for stretch on the bench. I will say that new chains wear and stretch more when new and then remain a constant length for many miles. I would find the new chains loose on race engines after just a few hours and have to adjust the mechanical tensioners, if they were used they would not need the adjustment. New sprockets also tend to exacerbate this problem.
